Answer 1

Answer:

Flowers rely on bees to cross-pollinate their female plants. When bees feed on the pollen, their body picks up excess via their pollen-collecting hairs, which is then released when they land. Pollen act as the flower's seed, which is mandatory for the survival of that flower species.

Answer 2

Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
